Description

L'invention est relative à un dispositif d'assemblage d'éléments longitudinaux tels que tubes, barres ou autres, destiné notamment à la construction d'échafaudages, gradins, charpentes ou autres structures démontables. Elle concerne l'industrie en particulier les utilisateurs de constructions métalliques amovibles.The invention relates to a device for assembling longitudinal elements such as tubes, bars or the like, intended in particular for the construction of scaffolding, steps, frames or other removable structures. It concerns industry in particular the users of removable metal constructions.

Dans de nombreux domaines d'activités, il est nécessaire de pouvoir créer des structures configurables selon les circonstances. Par exemple, dans la construction de bâtiments, il est nécessaire de pouvoir installer des échafaudages dont la hauteur et la largeur dépendent du site. Il en est de même pour la confection de stands dans des halls d'exposition où la taille de la charpente dépend de la surface allouée pour la mise en place du stand.In many fields of activity, it is necessary to be able to create structures that can be configured according to the circumstances. For example, in the construction of buildings, it is necessary to be able to install scaffolding whose height and width depend on the site. The same is true for the making of stands in exhibition halls where the size of the frame depends on the surface allocated for setting up the stand.

Les exemples d'utilisation d'éléments longitudinaux bien souvent qui se présentent sous la forme de tubes profilés pour former une armature sont très nombreux, Bien entendu, la section et la longueur des tubes dépendent de l'emploi qui en est fait, toutefois, en toute circonstance, il est utilisé un dispositif d'assemblage pour précisément fixer les tubes les uns aux autres.The examples of use of longitudinal elements very often which are in the form of profiled tubes to form a reinforcement are very numerous, Of course, the section and the length of the tubes depend on the use which is made of it, however, in all circumstances, an assembly device is used to precisely fix the tubes to each other.

Actuellement, on connait deux principaux types d'éléments d'assemblage. Il s'agit pour les constructions extrêmement légères de pièces de profilés soudés en angle par le fabricant. L'utilisateur alors doit enfiler les extrémités des longerons à solidariser dans les profilés soudés en équerre, ce qui permet de positionner les pièces, ensuite le bridage des longerons est obtenu par exemple à l'aide d'une goupille.Currently, there are two main types of assembly elements. These are extremely light constructions of profile parts welded at an angle by the manufacturer. The user then has to thread the ends of the beams to be joined in the profiles welded at an angle, which makes it possible to position the parts, then the clamping of the beams is obtained for example using a pin.

Pour pouvoir réaliser différents montages, le fabricant est amené a proposer à sa clientèle toute une série de dispositifs d'assemblage soudés avec un nombre de raccords différents et selon des angles également distincts. Ceci amène à devoir offrir une gamme très étendue d'éléments d'assemblage qui ne peuvent toutefois couvrir tous les besoins de calage angulaire étant donnée leur affinité.To be able to carry out different assemblies, the manufacturer is led to offer its customers a whole series of assembly devices welded with a number of different fittings and at equally distinct angles. This leads to having to offer a very wide range of assembly elements which cannot, however, cover all the angular setting needs given their affinity.

Dans ces conditions, ce type d'assemblage est essentiellement utilisé dans le cas de configurations fixes pour réaliser une structure donnée. L'utilisateur aura donc à commander au fabricant uniquement les pièces dont il a besoin pour la construction souhaitée. Il sera très difficile par la suite de modifier la géométrie de la construction à moins d'acquérir de nouvelles pièces spécifiques au nouvel assemblage.Under these conditions, this type of assembly is essentially used in the case of fixed configurations to produce a given structure. The user will therefore have to order from the manufacturer only the parts he needs for the desired construction. It will then be very difficult to modify the geometry of the construction unless you acquire new parts specific to the new assembly.

Ainsi, les défauts de cette technique sont une relative faiblesse étant donné qu'il s'agit de pièces légères, une absence totale de réglage du calage angulaire entre les différents éléments longitudinaux à assembler, ce qui oblige à disposer d'un nombreux choix de dispositifs d'assemblage pour pouvoir répondre aux différentes configurations susceptibles d'être rencontrées.Thus, the faults of this technique are a relative weakness since they are light parts, a total absence of adjustment of the angular setting between the various longitudinal elements to be assembled, which requires having a large choice of assembly devices to be able to respond to the various configurations likely to be encountered.

Etant donné qu'il n'est pas toujours possible de se limiter à un type de construction, les fabricants de matériels d'échafaudage par exemple proposent comme autre type de dispositifs d'assemblage un système de fixation à bride.Since it is not always possible to be limited to one type of construction, the manufacturers of scaffolding equipment, for example, propose as another type of assembly device a flange fixing system.

Ces dispositifs comportent des coquilles qui viennent se positionner de part et d'autre de l'élément longitudinal à assembler, et de moyens de serrage vis-écrou qui solidarisent le tube avec la bride pincée entre les coquilles. La forme géométrique de la bride permet d'assembler deux tubes à angle droit.These devices include shells which are positioned on either side of the longitudinal element to be assembled, and screw-nut tightening means which secure the tube with the clamp clamped between the shells. The geometric shape of the flange allows two tubes to be assembled at right angles.

Une fabrication particulière permettrait d'envisager un autre calage angulaire. Il faut toutefois noter que ces dispositifs ne sont absolument pas universels. En effet, ils permettent d'assembler deux profilés bout à bout ou deux profilés en équerre. Tout autre assemblage demande la fabrication d'une bride spécifique.A particular manufacturing would allow to consider another angular setting. However, it should be noted that these devices are by no means universal. Indeed, they allow to assemble two end-to-end profiles or two angle profiles. Any other assembly requires the manufacture of a specific flange.

Outre cette spécificité, qui limite les utilisations et réalisations envisageables, le système de serrage à vis-écrou est particulièrement long à mettre en oeuvre.In addition to this specificity, which limits the possible uses and embodiments, the screw-nut tightening system is particularly long to implement.

La principale difficulté rencontrée pour la mise au point d'un dispositif d'assemblage universel est le verrouillage du positionnement angulaire. En effet, on connait des supports à tubes articulés qui utilisent pour leur verrouillage un mécanisme à serrage. Cependant, ces mécanismes ne sont pas fiables sur le plan du verrouillage étant donné qu'un manque de serrage crée un glissement des pièces.The main difficulty encountered in the development of a universal assembly device is the locking of the angular positioning. Indeed, there are known articulated tube supports which use for their locking a clamping mechanism. However, these mechanisms are not reliable in terms of locking since a lack of tightening creates a sliding of the parts.

Ainsi, cette technique d'assemblage permet d'obtenir des rigidités élevées mais les défauts de réglage du calage angulaire sont toujours présents. Par conséquent, ces brides ne permettent pas d'apporter une solution générale et de plus le système vis-écrou est long à mettre en oeuvre.Thus, this assembly technique makes it possible to obtain high rigidities, but the defects in adjusting the angular setting are still present. Consequently, these flanges do not make it possible to provide a general solution and, moreover, the screw-nut system is long to implement.

Le but principal de la présente invention est de présenter un dispositif d'assemblage d'éléments longitudinaux, qui assure une possibilité d'assemblage de deux à quatre pièces, avec un positionnement angulaire ajustable et verrouillable. Ainsi, l'utilisateur pourra réaliser des constructions d'armatures de géométries très diverses par simple réglage des dispositifs d'assemblage. Des garanties de sécurité sont offertes grâce au verrouillage du positionnement angulaire, ce verrouillage n'étant pas directement lié à la force de serrage mis en oeuvre pour bloquer le réglage du positionnement angulaire de l'élément d'assemblage de la présente invention.The main object of the present invention is to present a device for assembling longitudinal elements, which ensures the possibility of assembling two to four parts, with a adjustable and lockable angular positioning. Thus, the user will be able to construct reinforcements of very different geometries by simply adjusting the assembly devices. Security guarantees are offered by locking the angular positioning, this locking not being directly linked to the clamping force used to block the adjustment of the angular positioning of the assembly element of the present invention.

Un autre avantage de l'élément d'assemblage de la présente invention est la rapidité de sa mise en oeuvre. En effet, outre le fait que le réglage du calage angulaire est très rapide, les systèmes de fixation proposés sont également très faciles à employer.Another advantage of the assembly element of the present invention is the speed of its implementation. Indeed, in addition to the fact that the adjustment of the angular setting is very fast, the proposed fixing systems are also very easy to use.

Un autre avantage de l'élément d'assemblage de la présente invention consiste en sa réalisation structurelle à partir de deux éléments complémentaires, qui dans un mode de réalisation, peuvent être identiques. Ainsi, la fabrication du dispositif d'assemblage sera limitée à l'usinage d'un seul élément, utilisé deux fois, les deux éléments étant positionnés symétriquement entre eux.Another advantage of the assembly element of the present invention consists in its structural production from two complementary elements, which in one embodiment, may be identical. Thus, the manufacture of the assembly device will be limited to the machining of a single element, used twice, the two elements being positioned symmetrically between them.

D'autres buts et avantages de la présente invention apparaitront au cours de la description qui va suivre qui n'est cependant donnée qu'à titre indicatif.Other objects and advantages of the present invention will appear during the description which follows which is however given only for information.

Selon l'invention, le dispositif d'assemblage d'éléments longitudinaux, tels que tubes, barres ou autres profils, destiné notamment à la construction d'échafaudages, gradins ou autres structures, est caractérisé par le fait qu'il présente des moyens pour ajuster et verrouiller le calage angulaire des éléments longitudinaux.According to the invention, the device for assembling longitudinal elements, such as tubes, bars or other profiles, intended in particular for the construction of scaffolding, steps or other structures, is characterized in that it has means for adjust and lock the angular setting of the longitudinal elements.

L'invention sera mieux comprise à la lecture de la description suivante accompagnée de dessins en annexe parmi lesquels:

  • - la figure 1 schématise l'assemblage de deux éléments longitudinaux,
  • - la figure 2 illustre l'assemblage de quatre éléments longitudinaux,
  • - la figure 3 montre un mode préférentiel de réalisation de l'élément d'assemblage d'éléments longitudinaux selon la présente invention,
  • - les figures 4a, b, c représentent différents modes d'exécution des moyens de verrouillage du calage angulaire de l'élément d'assemblage selon la présente invention.
The invention will be better understood on reading the following description accompanied by attached drawings, among which:
  • - Figure 1 shows schematically the assembly of two longitudinal elements,
  • FIG. 2 illustrates the assembly of four longitudinal elements,
  • FIG. 3 shows a preferred embodiment of the element for assembling longitudinal elements according to the present invention,

La présente invention vise un dispositif d'assemblage d'éléments longitudinaux, tels que tubes, barres ou autres profils, destiné notamment à la construction d'échafaudages, de gradins ou autres structures amovibles. Elle concerne principalement les utilisateurs d'armatures métalliques pour constructions légères.The present invention relates to a device for assembling longitudinal elements, such as tubes, bars or other profiles, intended in particular for the construction of scaffolding, steps or other removable structures. It mainly concerns users of metal reinforcements for light constructions.

Le dispositif d'assemblage d'éléments longitudinaux selon la présente invention a précisément pour objectif d'apporter une solution aux différentes configurations de géométries de liaison susceptibles d'être rencontrées.The purpose of the device for assembling longitudinal elements according to the present invention is precisely to provide a solution to the different configurations of connection geometries that may be encountered.

La figure 1 représente le cas le plus simple c'est-à-dire l'assemblage de deux éléments longitudinaux 1 et 2 entre eux. Le dispositif d'assemblage 3 selon la présente invention est bien entendu interposé entre les éléments 1 et 2 et il offre l'avantage de permettre le réglage d'une inclinaison libre de l'un des éléments par rapport à l'autre, comme cela est schématisé par les flèches 4.FIG. 1 represents the simplest case, that is to say the assembly of two longitudinal elements 1 and 2 between them. The assembly device 3 according to the present invention is of course interposed between the elements 1 and 2 and it offers the advantage of allowing the adjustment of a free inclination of one of the elements relative to the other, like this is shown diagrammatically by the arrows 4.

Selon la caractéristique principale de la présente invention, le dispositif d'assemblage 3 présente des moyens pour ajuster et verrouiller le calage angulaire des éléments longitudinaux 1 et 2.According to the main characteristic of the present invention, the assembly device 3 has means for adjusting and locking the angular setting of the longitudinal elements 1 and 2.

Ainsi, on règle le positionnement angulaire puis on verrouille les pièces, ce qui garantit la sécurité et évite un déréglage accidentel du calage angulaire.Thus, the angular positioning is adjusted and then the parts are locked, which guarantees safety and avoids accidental misalignment of the angular setting.

Toutefois, le dispositif d'assemblage d'éléments longitudinaux de la présente invention ne se limite pas qu'à la liaison de deux tubes 1 et 2 mais il est possible d'envisager la liaison jusque quatre tubes, comme cela est illustré à la figure 2.However, the device for assembling longitudinal elements of the present invention is not limited to the connection of two tubes 1 and 2 but it is possible to envisage the connection up to four tubes, as illustrated in the figure. 2.

L'inclinaison entre les tubes 1 et 2 en vis-à-vis peut toujours être modifiée, telle que schématisée par les flèches 4, par contre, les tubes 5 et 6 sont fixes. Il est possible d'envisager un positionnement incliné coaxial ou non des tubes 5 et 6 à condition de concevoir le dispositif d'assemblage 3 pour le cas d'espèces. En pratique, il s'avère qu'avec le positionnement ajustable des éléments longitudinaux 1 et 2, cela s'avère amplement suffisant.The inclination between the tubes 1 and 2 facing each other can always be modified, as shown diagrammatically by the arrows 4, on the other hand, the tubes 5 and 6 are fixed. It is possible to envisage an inclined positioning coaxial or not of the tubes 5 and 6 provided that the assembly device 3 is designed for the case of species. In practice, it turns out that with the adjustable positioning of the longitudinal elements 1 and 2, this is more than enough.

Une réalisation intermédiaire peut parfaitement être envisagée avec l'assemblage de trois tubes.An intermediate embodiment can perfectly be envisaged with the assembly of three tubes.

Selon l'invention, le dispositif d'assemblage est formé de deux pièces 7 et 8, telles qu'illustrées à la figure 3. Ces deux pièces comprennent chacune au moins un embout 9 de raccordement à l'extrémité d'un élément longitudinal, non représenté.According to the invention, the assembly device is formed of two parts 7 and 8, as illustrated in FIG. 3. These two parts each comprise at least one end piece 9 for connection to the end of a longitudinal element, not shown.

De nombreuses solutions peuvent être envisagées au niveau de ce raccordement et en particulier l'exécution dépendra du profil de l'élément longitudinal. En supposant qu'il s'agisse d'un élément tubulaire, la solution préconisée consiste en la formation d'un tenon 9 qui viendra s'emmancher à l'extrémité de l'élément tubulaire. Pour faciliter l'introduction du tenon 9, de préférence celui-ci présente un profil cônique.Many solutions can be envisaged at this connection and in particular the execution will depend on the profile of the longitudinal element. Assuming that it is a tubular element, the recommended solution consists in the formation of a stud 9 which will be fitted at the end of the tubular element. To facilitate the introduction of the post 9, preferably it has a conical profile.

A titre d'exemple, le tenon 9 est traversé par un orifice 10 pour permettre l'adoption d'une fixation de l'élément tubulaire par goupilles. Toutefois, d'autres mises en oeuvre peuvent parfaitement être adoptées sans pour autant sortir du cadre de la présente invention, notamment un raccord vissé peut parfaitement être envisagé.For example, the post 9 is traversed by an orifice 10 to allow the adoption of a fixing of the tubular element by pins. However, other implementations can perfectly be adopted without departing from the scope of the present invention, in particular a screw connection can perfectly well be envisaged.

La pièce 7 comprend également une patte 11 traversée par un axe d'articulation 12 représenté en pointillés à la figure 3. La patte 11 porte également un système de verrouillage angulaire.The part 7 also includes a lug 11 crossed by a hinge pin 12 shown in dotted lines in FIG. 3. The lug 11 also carries an angular locking system.

Pour permettre la fixation d'un élément longitudinal transversal à l'axe de la pièce 7, comme cela est envisagé à la figure 2, un embout de raccordement 13 est mis en place sur la patte 11. Cet embout de raccordement 13 est tubulaire pour permettre l'accès à l'axe d'articulation 12 par son volume intérieur. L'embout 13 tubulaire pourra se raccorder à l'élément longitudinal par un emboitement extérieur ou intérieur. La fixation par goupilles à l'aide d'un orifice 14 reste envisageable.To allow the attachment of a longitudinal element transverse to the axis of the part 7, as envisaged in FIG. 2, a connection end piece 13 is placed on the tab 11. This connection end piece 13 is tubular for allow access to the hinge pin 12 by its internal volume. The tubular end piece 13 can be connected to the longitudinal element by an external or internal socket. Attachment by pins using an orifice 14 remains possible.

Selon un mode de construction présentée ici, l'axe d'articulation 12 est formé par une tige filetée 12 sur laquelle sont vissés deux écroux 15 et 16 qui déterminent le serrage des pièces 7 et 8. L'accès aux écrous 15 et 16 est réalisable même en présence d'embouts de raccordement 13 orthogonaux grâce à l'emploi de tubes pour la confection de ces derniers.According to a construction method presented here, the hinge pin 12 is formed by a threaded rod 12 on which are screwed two nuts 15 and 16 which determine the tightening of the parts 7 and 8. Access to the nuts 15 and 16 is achievable even in the presence of connection pieces 13 orthogonal through the use of tubes for making them.

Les systèmes de verrouillage présents sur les pattes des pièces 7 et 8 sont complémentaires sur chacune de ces pièces, c'est-à-dire que le verrouillage est assuré par emboitement de formes complémentaires. Pour déverrouiller les pièces, il est nécessaire de les écarter, c'est-à-dire que même avec un serrage minimum de l'axe d'articulation 12, le verrouillage est assuré puisqu'il n'est pas possible de déboiter les pièces l'une de l'autre,The locking systems present on the legs of the parts 7 and 8 are complementary on each of these parts, that is to say that the locking is ensured by interlocking of complementary shapes. To unlock the parts, it is necessary to separate them, that is to say that even with a minimum tightening of the hinge pin 12, the locking is ensured since it is not possible to dislodge the pieces from each other,

Il est judicieux de choisir un profil de verrouillage identique sur chacune des pièces 7 et 8, car ceci permet d'adopter une fabrication unique.It is a good idea to choose an identical locking profile on each of parts 7 and 8, as this allows you to adopt a unique manufacturing process.

Ainsi, dans un tel mode de réalisation, on autorisera la réalisation du dispositif d'assemblage à partir de deux pièces 7 et 8 de même forme et présentant un système de verrouillage identique. Une seule pièce devra donc être usinée selon des plans particuliers et l'assemblage sera formé par une disposition symétrique des deux pièces identiques selon le principe de l'invention.Thus, in such an embodiment, the production of the assembly device will be authorized from two parts 7 and 8 of the same shape and having an identical locking system. A single part must therefore be machined according to particular plans and the assembly will be formed by a symmetrical arrangement of the two identical parts according to the principle of the invention.

A titre d'exemple, les figures 4a, b, et c, représentent différentes solutions susceptibles d'être adoptées pour le système de verrouillage.By way of example, FIGS. 4a, b, and c show different solutions which can be adopted for the locking system.

A la figure 4a, le système de verrouillage est assuré par l'emboitement alterné de doigts 17 et orifices 18 complémentaires. Afin que les systèmes de verrouillage soient identiques sur chacune des pièces, un orifice 18 est toujours diamétralement opposé à un doigt 17 par rapport à l'axe d'articulation.In FIG. 4a, the locking system is ensured by the alternating interlocking of fingers 17 and complementary orifices 18. So that the locking systems are identical on each of the parts, an orifice 18 is always diametrically opposite a finger 17 relative to the axis of articulation.

Une autre variante est illustrée à la figure 4b, selon laquelle le système de verrouillage est formé de tenons 19 et mortaises 20. Ces systèmes permettent un réglage discret du calage angulaire. Par exemple, les réglages 0°, 30°, 45°, 60°, 90°, permettent d'apporter une solution dans la majorité des configurations existantes.Another variant is illustrated in FIG. 4b, according to which the locking system is formed of tenons 19 and mortises 20. These systems allow a discreet adjustment of the angular setting. For example, the settings 0 °, 30 °, 45 °, 60 °, 90 °, provide a solution in the majority of existing configurations.

Si toutefois, une plus grande finesse dans le réglage était nécessaire, alors il est préconisé d'utiliser un système de verrouillage à crans tel qu'illustré à la figure 4c. Selon ce système, une multitude de crans radiaux 21 sont usinés sur la surface de la patte 11 ce qui permet d'obtenir à la fois un verrouillage et un réglage fin du calage angulaire des deux pièces 7 et 8.If, however, greater finesse in the adjustment was necessary, then it is recommended to use a notched locking system as illustrated in FIG. 4c. According to this system, a multitude of radial notches 21 are machined on the surface of the tab 11, which makes it possible to obtain both a locking and a fine adjustment of the angular setting of the two parts 7 and 8.

Pour la fabrication du dispositif d'assemblage de la présente invention, on pourrait retenir le moulage des pièces dans un alliage d'aluminium. Des expériences ont permis d'établir que le dispositif d'assemblage était à même à supporter des éléments longitudinaux de grande portée de l'ordre de 15 m.For the manufacture of the assembly device of the present invention, one could retain the molding of the parts in an aluminum alloy. Experiments have established that the assembly device was able to support longitudinal elements of great range of the order of 15 m.

Il est possible d'envisager une conception rapportée de l'embout 13 de raccordement d'éléments longitudinaux transversaux. Selon cette conception, une rondelle est soudée à l'extrémité de l'embout 13 et cette rondelle percée d'un orifice est traversée par l'axe d'articulation 12 qui, dans ce cas, doit être de longueur plus importante. L'écrou est vissé sur la tige filetée 12 par l'intérieur de l'embout 13 qui alors se trouve emprisonné et fixé sur la patte 11 par l'intermédiaire de la tige filetée 12.It is possible to envisage an added design of the end piece 13 for connecting transverse longitudinal elements. According to this design, a washer is welded to the end of the end piece 13 and this washer pierced with an orifice is crossed by the hinge pin 12 which, in this case, must be of greater length. The nut is screwed onto the threaded rod 12 through the inside of the end piece 13 which is then trapped and fixed on the tab 11 by means of the threaded rod 12.

D autres mises en oeuvre de la présente invention à la portée de l'homme de l'art auraient également pu être envisagées sans pour autant sortir du cadre de celle-ci.Other implementations of the present invention within the reach of ordinary skill in the art could also have been contemplated without departing from the scope thereof.
